SUDOKU FOR FUN

(e)(n)=?

Complete the Sudoku puzzle as you would any other Sudoku:

The grid is composed of 81 squares and divided into nine blocks, each containing nine squares. The goal: each of the nine blocks has to contain all of the numbers 1 to 9 within its squares; each number can appear only once in a row, column, or box. In addition, each vertical nine-square column as well as each horizontal nine-square line across within the larger square must also contain the numbers 1-9 without repetition or omission. There is only one correct value for (e)(n).

Consider the following code as applied to the grid: Each column of Sudoku is defined by a letter from a-i and each row of Sudoku is defined by a letter from j-t.
